[Touch Pro, Fuze General] Scrtcwlvl:
As a project in my Statistics course we are asked to develop and carry out an experiment. Rather than do something conventional I felt pressed to do something that would actually be useful to myself and potentially the community.

-A comparative experiment of radio stacks' effect on battery usage will be done.

Now I realize there are many confounding variables that effect battery drain that are equally as important, location, usage, brightness, ram load and user use habits : however for the sake of the experiment I wish to see for each user how their battery drain changes based on the radio in their area on their usage. Because each users results will be directly compared with their own many of these confounding variables will be minimized as much as possible with such a short time frame to test.

The experiment will call for any available HTC Touch Pro users (World wide) starting May 18th to flash the official radios, each day trying a different radio and tracking the battery drain.

The current plan is to use the official released radios at

(Including the ATT Test rom radio but not the newer 1.14.25.05 due to issues and bugs confounding the results even more)

- Radio - Day of Trial - Date - My Resulting Percentage at end of day

-1.12.25.19 - Benchmark / Comparison test - May 18th - 40% at midnight

-1.02.25.11 - Day 2 - May 19th - 6%

-1.02.25.19 - Day 3 - May 20th - 15%

-1.02.25.28 - Day 4 - May 21st - 45% (gasp)

-1.08.25.20 - Day 5 - May 22nd - 3% (Battery Change out at 10:30pm) 87% on battery 2 - total - -10%

-1.01.25.16 - Day 6 - May 23rd - 14%

-1.02.25.32 - Day 7 - May 24th - 5% (Battery change out at 9:30pm) 51% on battery 2 - total - -44%

Just got a Touch HD - Had to take 2 days off the trial to play with the lovable device.

-1.02.25.27 - Day 8 - May 25th - (May 27th) - 3% (Battery Change out at 10:30pm) 98% on battery 2 - total - 1%

-1.02.25.31 - Day 9 - May 26th - (May 28th) - 43%

-1.11.25.01 - Day 10 - May 27th - (May 29th) - 10%

- End of Trial - For me -

I will wait a while to collect all available data from testers then perform the statistical analysis.

Conditions for testing:

Because each user is unique in exactly how they use their devices, 3G / 2G, Wifi, Bluetooth, GPS, I only ask that the usage be relatively consistent throughout the trial. As long as you are consistent with the other things draining your battery we can see exactly what it is that radios drain.

Each evening anyone willing to participate in the experiment will flash a new radio and track the battery drain over the following day.

In order to track battery usage, the performed method will simply be recording the remaining battery life percentage at the conclusion of the day. (usually a selected time by the user) This is due to no battery tracking application freely available that efficiently tracks battery levels without interrupted normal usage or battery life.

I apologize for the short time frame that has been created, however the project was developed months ago, yet the teacher simply dumped it on us to get the actual experiment done next week and I am truly hoping I can stir up enough interest and enough volunteers to get the data I need.

Please post if you have any interest in the project, wish to volunteer, or have a suggestion for which battery app to use.

I need volunteers and this is information that is helpful to everyone, so please take part and please help out.

If nothing else, I will post at least my own results to this little experiment.
